Description

Several nights of imaging went into this image. Every night was very good to excellent transparency, which helped the Integrated Flux nebula and Holmberg IX show better, but the seeing was very poor, contributing to the softer looking stars. Probably about 80% of this was shot with a large bright Moon in the sky as well.

Normally 300 seconds is plenty long for color, but this is the second time lately I have had to go back and shoot 600 seconds. Both times I happened to be shooting galaxies and I think I will start doing 600 seconds for my RGB on all galaxies now.
